<a name="gdk3-Wayland-Interaction.description"></a><h2>Description</h2>
<p>The functions in this section are specific to the GDK Wayland backend.
To use them, you need to include the <code class="literal">&lt;gdk/gdkwayland.h&gt;</code> header and use
the Wayland-specific pkg-config files to build your application (either
<code class="literal">gdk-wayland-3.0</code> or <code class="literal">gtk+-wayland-3.0</code>).</p>
<p>To make your code compile with other GDK backends, guard backend-specific
calls by an ifdef as follows. Since GDK may be built with multiple
backends, you should also check for the backend that is in use (e.g. by
using the <code class="function">GDK_IS_WAYLAND_DISPLAY()</code> macro).</p>
